How to remove the smell in the house

We all know that newly renovated houses have a special smell and are not suitable for living. However, sometimes due to some unavoidable reasons, we need to move into a newly renovated home. At this time, we need to open the windows every day to ventilate the house. For houses that have been lived in for a long time, there may be some musty smell, and they should also be properly ventilated. So how do you remove the smell in the house?

How to remove decoration odors:

1. Ventilation method

Through the circulation of indoor air. It can reduce the content of harmful substances in indoor air, thereby reducing the harm of such substances to the human body. In winter, people often close doors and windows, and the air cannot circulate between indoor and outdoor spaces. Not only will the formaldehyde content in the indoor air increase, but radon gas will also continue to accumulate and even reach a very high concentration.

Advantages: good effect, no cost Disadvantages: long time, generally it takes more than three years to remove formaldehyde.

2. Traditional methods

Soak 300 grams of black tea in two basins of water, put it into the room, and open the windows for ventilation. Within 48 hours, the indoor formaldehyde content will drop by more than 90%, and the irritating smell will be basically eliminated. Another option is to place some pineapples and other fruits indoors.

Advantages: The smell seems to be less. Disadvantages: It only uses a smell to cover up the odor of the decoration, and the harmful gas still exists in the room.

3. Solid adsorbent

Some components of solid adsorbents are porous adsorbents with large surface area and large pore volume. The principle of filtering gases and liquids by these substances is to absorb and adsorb the unnecessary parts of the filtered gas or liquid through their own sponge-like pores. The molecular diameter of the substance being filtered and adsorbed must be smaller than the pore size of the adsorbent. Conversely, if the molecular diameter of the substance being filtered is larger than the pore size of the adsorbent, adsorption cannot be achieved. The highly targeted natural rare earth minerals and synthetic adsorbents can overcome the weakness of activated carbon and bamboo charcoal that they are easily penetrated and re-emitted after adsorbing formaldehyde molecules. For stubborn formaldehyde molecules, adding targeted loading reactants has triple effects of passive adsorption, active absorption reaction removal and ion exchange capacity.

4. Activated carbon adsorption

Activated carbon has adsorption potential, which is formed by the attraction between carbon molecules and adsorbed molecules. The smaller the pore size, the stronger the adsorption potential. In addition, according to the theory of molecular motion, all objects are composed of molecules or atoms. There are gaps between them, and at the same time they are in a state of endless and irregular thermal motion, and molecules collide with each other frequently. According to relevant data, under standard conditions, the free movement speed of formaldehyde molecules is about 450 meters per second, and one formaldehyde molecule collides with other molecules 109 times per second. At this time, if the diameter of the colliding molecule matches the pores of the activated carbon, it will be adsorbed.
